ABSTRACT:
A blast joint resistant to erosion including an inner pipe joint having a substantially smooth outer surface and an upper end and a lower end. A cylindrical lower assembly having an exterior surface suitable for gripping with power tongs is mounted on the lower end of the inner pipe joint with a torque transfer assembly for transferring torque from the lower assembly to the smooth outer surface of the inner pipe joint. A cylindrical upper assembly having an exterior surface suitable for gripping with power tongs is mounted on the upper end of the inner pipe joint. A plurality of erosion resistant rings are concentrically mounted on the inner pipe joint in a vertically continuous arrangement from a point near the lower end to a point near the upper end of the inner pipe joint without a vertical gap between the rings. A hydrostatic piston and cylinder loader provides a vertical load on the plurality of rings to prevent separations between the rings.
